We recommend storing at room temperature between 65 and 75 degrees. You should never store them in your freezer or on the dash board in your car!
Customers who live in very cold or hot climates may be concerned about delivery since your package may sit on your porch under a mound of snow, or on a rocking chair in direct sunlight. This will not negatively affect your cartridges or flings since this is short term.
Prolonged exposure, or repeated hot and cold exposure should be avoided.
